My team wants to trigger a nurture journey in SFMC Journey Builder when SFDC Leads/Contacts fill out a web form. If the web visitor is net new to our company it will get created as a SFDC Lead in SFDC CRM and will enter the SFMC journey as a SFDC Lead. My colleagues created some decision splits that contain SFDC CRM Contact object fields after different wait steps to check specific SFDC Contact fields if the original SFDC Lead got converted while the Lead was moving along the journey.
In other words, can we reference Contact attributes after a Lead got converted while still going through a journey?
How does Journey Builder manage IDs upon Lead to Contact conversions? For instance, if a SFDC Lead gets converted while being in a journey, does Journey Builder automatically knows what is the SFDC Contact Id?
